New closer Jim Johnson agreed to a $10 million, one-year contract with the A's on Thursday.

Catcher John Jaso also reached agreement on a $2.3 million, one-year deal.

The A's acquired Johnson, the 2013 AL saves leader, last month in a trade with Baltimore. He converted 50 of 59 save opportunities in 2013, going 3-8 with a 2.94 ERA. He was tied with Atlanta's Craig Kimbrel for the major-league saves lead.

Jaso gets a $500,000 raise under the deal announced Thursday. In addition, Jaso can earn $25,000 bonuses for 90 games started at catcher and 450 plate appearances.

His first season with the two-time defending AL West champion A's was cut short after he suffered a concussion when he took a foul tip off his mask July 24 at Houston and complained of a headache. Initially, Jaso was placed on the seven-day concussion list the following day, then transferred to the 15-day disabled list Aug. 8.

Jaso batted .271 with three homers and 21 RBIs in 70 games.

Replay approved: Major League Baseball will greatly expand instant replay to review close calls starting this season.

MLB announced that owners, players and umpires have approved the new system.

Each manager will be allowed to challenge at least one call per game. If he's right, he gets another challenge. After the seventh inning, a crew chief can request a review on his own if the manager has used his challenges.

The so-called "neighborhood play" at second base on double plays cannot be challenged. Many had safety concerns for middle infielders being wiped out by hard-charging runners if the phantom force was subject to review.

All reviews will be done by current MLB umpires at a replay center in MLB.com's New York office.

Joe Torre, MLB's executive vice president of baseball operations, said work continues on a proposed rule that would ban home-plate collisions between runners and the catcher - the so-called Buster Posey rule. The rule has not been written and talks on its content are ongoing between MLB representatives and the players union, Torre said.

A-Rod talks: During a late Wednesday night promotional appearance in Mexico City, Alex Rodriguez says his season-long suspension could be a benefit, allowing him to rest and return to the Yankees for the final three years of his contract.

Rodriguez, in his first public comments since arbitrator Fredric Horowitz's decision Saturday, said he wanted to end his career with New York. "The 2014 season could be a big help for me," Rodriguez said. "It might serve as a break and close the chapter, and begin in 2015 with my last three years under contract with the Yankees."
